I'm currently working an LTS resource position and I got pulled to cover a 4/5 combo for the last hour of the day yesterday. The teacher left a writing assignment which should have been pretty straightforward, but as the students had been testing during the morning, they were really not in the mood to put their heads down and do actual work. I turned on the ELMO and wrote a note for the teacher that they all could see. I laid it on super thick--the kind of note I'd never actually leave for a teacher. I said they were noisy, they were not following directions, they were walking around the room--all of which were true. When they started reading what I was writing, that room got quiet so fast, it was as if someone flipped the noise switch! I looked up and everyone was working. The silence didn't last long, but it was effective enough that I'll do it again. After the sudents left I tore it up and wrote a much less dramatic note for the teacher.
